Thank you for the sample project.
I did a bit of testing and this looks like it has been fixed on ue5-main as the canal loads as intended.
I can attempt to look around for the specific fix if you’d like.
That being said, testing it out on 5.5.4 I found a couple workarounds:
1.) Increasing loading range to something like 8000+ has it stream in
2.) Place a streaming volume around the mesh to force it to load early
3.) Moving the actors closer to the origin, I noticed with it being so far out it could be miscalculating something
Rearranging the objects to be around the origin had it work as intended; for reference the new vectors were:
Cube: 1169.325697 674.44672 -302.000512
Canal: 5413.993218 -21.73352 -94.000512
Player start and floor: 0 0 0
Please let me know what you think!
